An improved prosthetic mitral valve (90) is provided having advantageous hemodynamic performance, nonthrombogenicity, and durability. The valve (90) includes a valve body (92) having an inflow annulus (150) and an outflow annulus. Commissural attachment locations (154) are disposed adjacent the outflow annulus. An anterior leaflet (98) and a posterior leaflet (100) of the valve (90) are shaped differently from one another. The inflow annulus (150) perferably is scalloped so as to have a saddle-shaped periphery having a pair of relatively high portions (162, 164) separated by a pair of relatively low portions (174, 176). The anterior high portion (162) perferably is verically higher than the posterior high portion (164). |
